An Exterior Insulation Finishing System (EIFS), also known as EWI (Exterior Wall Insulation Systems) or External Thermal Insulation Composite Systems (ETICS) is a type of cladding system that provides exterior walls with an insulated finished surface and waterproofing in an integrated composite material system.

Cellulose Ether HPMC/MHPC offers the following advantages to EIFS/ETICS:
● Improved adhesion: The materials of the exterior walls are firmly held together by using this cellulose material.
● The adequate wetting ability for EPS board and substrate:Cellulose Ether HPMC/MHPC improves how effective the wetting of the board and substrate.
● Reduced air entrancement and water uptake: The air spaces within the external walls of buildings become resistant to the passage of air, which may weaken the structure. Water uptake is reduced as well, Cellulose Ether HPMC/MHPC increases the water retention of the walls and this does not allow water uptake.
● Good consistency: This cellulose allows the walls to maintain a consistent finish look and appearance, and this adds beauty to the walls.
● Good anti-bleeding:Cellulose Ether HPMC/MHPC prevents the occurrence of bleeding within the exterior walls
● Anti-crack and anti-shrinkage: The occurrence of wall cracks and shrinkages are prevented with the use of Hydroxypropyl methylcellulose.
● Good workability: It also offers good workability. The designated particle size distribution assures quick or lumps free dissolution. It is suitable for all conventional mineral and organic binders.
